Description	Seven methods for estimating daily global radiation, RG, were tested in the Central Europe case study area (lowlands of Austria and the Czech Republic) assuming that no measured global radiation data for parameterisation are available, i.e. with all empirical coefficients required by the selected methods being obtained from previously published studies. The variability explained (R2), the root mean square error (RMSE) and mean bias error (MBE) indicated that the highest precision could be expected when sunshine duration was used as predictor. The method generally known as the ?ngström–Prescott method explained 96% of the RG variability with the RMSE value (annual mean) equalling 1.6 MJ m?2 day?1 and MBE being 0.1 MJ m?2 day?1. It was found to be ultimately the best of all tested methods.
